In the preparation of compounds of formula (I), the following alternative scheme may be chosen.

In scheme 4, G, Y₁, Y₂, Y₃, V₄ have the meanings as defined for compounds of formula I.

Step 1

The thione intermediate may be directly transformed into compound M whereby the thione starting material is reacted with hydrazine hydrate to give compound M.

Analogous transformations are to be found in the literature and include the following: Australian Journal of Chemistry, 35(6), 1263-7; 1982; Heterocyclic Communications, 14(6), 469-472; 2008; Indian Journal of Chemistry, Section B: Organic Chemistry Including Medicinal Chemistry, 27B(3), 298-300; 1988; WO 2005/077939.

Step 2 is already described in scheme 2, step 3 above.

Step 3

Deviating from the sequence in the previous scheme 2, the methyl-thio intermediate is oxidized either to the methyl sulfoxide or to the methyl sulfone. A large variety of oxidants can be used. Such oxidants include hydrogen peroxide or hydrogen peroxide-urea adduct in the presence of an acid such as acetic acid or trifluoroacetic acid. Oxidants include also the use of peracids such as meta-chloroperbenzoic acid, peracetic acid or trifluoroperacetic acid. Such peracids can be used as such, or, alternatively, they can be generated in situ from the corresponding acids and hydrogen peroxide or the corresponding acid anhydride and hydrogen peroxide. Still other oxidants include permanganates, such as sodium or potassium permanganate, or MeReO₃ and hydrogen peroxide. Depending upon the reaction time and the stoichiometry, the reaction can be tuned either towards the formation of the sulfoxide or the sulfone. Furthermore, if a mixture of both the sulfoxide and the sulfone is obtained they can usually be separated by chromatography.

To obtain the chloride, reagents such as POCl₃, (Cl₃CO)₂C═O with a base such as pyridine are used. In order to obtain the bromide, reagents such as POBr₃ and PBr₃ are used. These transformations can be done neat or in the presence of (an) inert solvent(s) such as CH₂Cl₂, ClCH₂CH₂Cl, CHCl₃, CCl₄, AcOEt, THF, dioxane, toluene, chloro-benzene, cyclohexane or sulfolane. The transformations can be done in the presence of a base such as pyridine, N,N-dimethylaniline or N,N-diethylaniline. The iodo derivative is usually prepared from the chloro or bromo analogues.

Step 5

This step is the same as step 1 in scheme 4 above.

In scheme 6, G, Y₁, Y₂, Y₃, V₃, V₄ have the meanings as defined for compounds of formula I.

Each U′ is independently of the other H, (tert-butyl)-O—CO, allyl-O—CO, benzyl-O—CO, HC(═O), C₁-C₆-alkyl-O—CO or C₁ C₆-alkyl-CO, or both U′ together with the nitrogen atom to which they are attached form one of the following cycles:

Typical such compounds N′ are either available commercially or are described in the literature. Alternatively, intermediates N′ may be a silylated or persilylated form of the aminotriazole, wherein U′ is tri-(C₁-C₆-alkyl)-silyl, preferentially trimethylsilyl. Partially or fully silylated form of intermediates N′ are obtained by treating a given compound of formula N′ wherein U′ is H with a silylating agent. This may be performed either with or without a solvent being present, and optionally in the presence of a catalyst such as Et₃N, (NH₄)₂SO₄ or CF₃SO₂OSiMe₃.

The preferred trimethylsilylation may consist of treating N′ wherein U′ is H, with a trimethylsilylating agent such as Me₃SiCl, Me₃SiBr, (Me₃Si)₂NH or MeC(═NSiMe₃)—O—SiMe₃. This may be performed either with or without an inert solvent, such as DMF, NMP, dimethylacetamide, MeCN, toluene being present, and optionally in the presence of a catalyst such as Et₃N, (NH₄)₂SO₄ or CF₃SO₂OSiMe₃. Relevant references for analoguous transformations include Organic Reactions 55, 1; 2000; Synthesis, (8), 773-8; 1992; Synthetic Communications, 34(5), 917-932; 2004

Step 1

This transformation consists of condensing an optionally protected amino triazole derivative with an electrophilic 3H-imidazo[4,5-c]pyridine derivative having a leaving group X″ in the 2-position. Leaving group X″ is selected from F, Cl, Br, I, SMe, SOMe and SO₂Me. In the course of the condensation reaction, the leaving group is displaced by the nitrogen atom of the triazole derivative to give the [1H-1,2,4-triazol-5-yl]amino substituent, optionally protected at the amino group.

Appl., 330959, 6 Sep. 1989, Russian Journal of Organic Chemistry (Translation of Zhurnal Organicheskoi Khimii), 34(7), 1032-1039; 1998; Russian Journal of Organic Chemistry (Translation of Zhurnal Organicheskoi Khimii), 37(8), 1158-1168; 2001

Step 2

In this step the amine is generated from the bis-amino-protected precursor. Such deprotection steps are standard procedures and well documented in the literature. When the protecting group is BOC, the deprotection is described in scheme 8, step 3. In some cases e.g. when U′ is C₁-C₆-alkyl-CO, the deprotection consists of a hydrolysis preferentially under acidic conditions.

Transformation 1

The acylation at the amino function is usually carried out using an acyl chloride (Cl—CO—U″) or carboxylic acid anhydride (U″—CO—O—CO—U″ or e.g. U″—CO—O—CO—C(CH₃)₃). Typical solvents used include CH₂Cl₂, CHCl₃, ClCH₂CH₂Cl, diethyl ether, THF, dioxane, toluene, cyclohexane, pyridine, ethyl acetate, MeCN. The reaction is typically done in the presence of a base such as Hünig's base or triethylamine. The acylation can be done with or without an acylation catalyst such as pyridine, 4-dimethylamino-pyridine or 4-pyrrolidino-pyridine. Most often, such acylation catalysts are used together with a base such as triethylamine or Hünig's base. In certain cases the reaction is carried out in water in the presence of an inorganic base such as sodium or potassium hydroxide or carbonate.

Step 1 was already dealt with in scheme 7, transformation 2.

Step 2

This is an alkylation of a BOC-protected secondary amine. The process is not limited to the use of a BOC-protected amine, though; an acetyl protected amine could be used instead, for example. The BOC protecting group is chosen to illustrate the principle.

The BOC-protected amine is treated with a base such as sodium hydride, LDA, sodium or potassium alcoholate (e. g. tert-butylate), sodium or potassium carbonate, and with an alkylating agent. Such alkylating agents include Cl—V₁′, Br—V₁′, I—V₁′, MeSO₂O—V₁′, p-Me-C₆H₄—SO₂O—V₁′, CF₃SO₂O—V₁′. Preferred solvents to carry out this transformation include diethyl ether, THF, dioxane, toluene, DMF, NMP, much depending on the chosen reaction conditions.

Appl., 2006107923, 12 Oct. 2006; Journal of Medicinal Chemistry, 32(2), 409-17; 1989; PCT Int. Appl., 2006107923, 12 Oct. 2006; Bioorganic & Medicinal Chemistry Letters, 16(11), 2842-2845; 2006

Step 3

This step consists of removing the BOC-protecting group. This is suitably carried out under acidic conditions. These include mixtures of CH₂Cl₂ and trifluoro acetic acid (e.g. using the two components in a 1:1 ratio (v:v)), trifluoro acetic acid alone, acetic acid (preferably at elevated temperature), HCl in a number of solvents (e.g. water, diethyl ether, MeOH) or HBr in acetic acid.

Appl. Publ., 20090186879, 23 Jul. 2009

Step 4

This step consists of alkylation, alkenylation, alkynylaton or benzylation of a secondary amine to obtain a tertiary amine. Typically the secondary amine is treated with a strong base such as sodium hydride or LDA, followed by the addition of an alkylating agent, for example. Such alkylating agents include Cl—V₂′, Br—V₂′, I—V₂′, MeSO₂O—V₂′, p-Me-C6H4-SO₂O—V₂′ and CF₃SO₂O—V₂′. For the case where V₂′ is methyl or ethyl, preferred reagents are MeO—SO₂—OMe and EtO—SO₂—OEt.

where the meanings of G, Y₁, Y₂, Y₃, V₃ and V₄ are as defined for compounds of formula I.

X″ is a halogen, preferably Cl, Br or I. More preferably X″ is Br

Step 1

The step consist of a Suzuki, Stille, Sonogashira or other similar cross coupling reactions. Typically, the halogenated starting material, preferably chloro, bromo or iodo, is reacted with an acetylene or an organometallic reagent of formula M[G-Y1], wherein M is InCl₂, InCl(G-Y1), In(G-Y1)₂, MgCl, MgBr, Sn(R₇)₃, ZnCl, ZnBr or B(OR₇)₂, wherein either R₇ is independently from each other hydrogen, C₁-C₆alkyl or wherein two R₇ together can form a C₃-C₈cycloalkyl, and a catalyst, such as tetrakistriphenylphosphinepalladium, palladium dichloride, [1,1-bis(diphenylphosphino) ferrocene]dichloropalladium(II), palladium acetate or bis(diphenylphosphine)palladium(II) chloride.

It has now been found that the compounds of formula (I) according to the invention have, for practical purposes, a very advantageous spectrum of activities for protecting useful plants against diseases that are caused by phytopathogenic microorganisms, such as fungi, bacteria or viruses.

The invention therefore also relates to a method of controlling or preventing infestation of useful plants by phytopathogenic microorganisms, especially fungi, wherein a compound of formula (I) is applied as active ingredient to the plants, to parts thereof or the locus thereof. The compounds of formula (I) according to the invention are distinguished by excellent activity at low rates of application, by being well tolerated by plants and by being environmentally safe. They have very useful curative, preventive and systemic properties and are used for protecting numerous useful plants. The compounds of formula (I) can be used to inhibit or destroy the diseases that occur on plants or parts of plants (fruit, blossoms, leaves, stems, tubers, roots) of different crops of useful plants, while at the same time protecting also those parts of the plants that grow later e.g. from phytopathogenic microorganisms.

It is also possible to use compounds of formula (I) as dressing agents for the treatment of plant propagation material, in particular of seeds (fruit, tubers, grains) and plant cuttings (e.g. rice), for the protection against fungal infections as well as against phytopathogenic fungi occurring in the soil.

Furthermore the compounds of formula (I) according to the invention may be used for controlling fungi in related areas, for example in the protection of technical materials, including wood and wood related technical products, in food storage or in hygiene management.

The compounds of formula (I) are particularly effective to protect useful plants or plant propagation material thereof against phytopathogenic fungi belonging to the following classes: Ascomycetes (e.g. the genus Cochliobolus, Colletotrichum, Fusarium, Gaeumannomyces, Giberella, Monographella, Microdochium, Penicillium, Phoma, Pyricularia, Magnaporthe, Septoria, Pseudocercosporella, Tapesia and Thielaviopsis); Basidiomycetes (e.g. the genus Phakopsora, Puccinia, Rhizoctonia, Thanatephorus, Sphacelotheca, Tilletia, Typhula and Ustilago); Fungi imperfecti (also known as Deuteromycetes; e.g. the genus Ascochyta, Diplodia, Erysiphe, Fusarium, Helminthosporium, Phomopsis, Pyrenophora and Verticillium); Oomycetes (e.g. Aphanomyces, Peronospora, Peronosclerospora, Phytophthora, Plasmopara, Pseudoperonospora, Pythium); and Zygomycets (e.g. the genus Rhizopus).

Within the scope of the invention, useful plants to be protected typically comprise the following species of plants: cereal (wheat, barley, rye, oat, rice, maize, sorghum and related species); beet (sugar beet and fodder beet); pomes, drupes and soft fruit (apples, pears, plums, peaches, almonds, cherries, strawberries, raspberries and blackberries); leguminous plants (beans, lentils, peas, soybeans); oil plants (rape, mustard, poppy, olives, sunflowers, coconut, castor oil plants, cocoa beans, groundnuts); cucumber plants (pumpkins, cucum-bers, melons); fibre plants (cotton, flax, hemp, jute); citrus fruit (oranges, lemons, grapefruit, mandarins); vegetables (spinach, lettuce, asparagus, cabbages, carrots, onions, tomatoes, potatoes, paprika); lauraceae (avocado, cinnamomum, camphor) or plants such as tobacco, nuts, coffee, eggplants, sugar cane, tea, pepper, vines, hops, bananas and natural rubber plants, as well as ornamentals.

The term “useful plants” is to be understood as including also useful plants that have been rendered tolerant to herbicides like bromoxynil or classes of herbicides (such as, for example, HPPD inhibitors, ALS inhibitors, for example primisulfuron, prosulfuron and trifloxysulfuron, EPSPS (5-enol-pyrovyl-shikimate-3-phosphate-synthase) inhibitors, GS (glutamine synthetase) inhibitors or PPO (protoporphyrinogen-oxidase) inhibitors) as a result of conventional methods of breeding or genetic engineering. An example of a crop that has been rendered tolerant to imidazolinones, e.g. imazamox, by conventional methods of breeding (mutagenesis) is Clearfield® summer rape (Canola). Examples of crops that have been rendered tolerant to herbicides or classes of herbicides by genetic engineering methods include glyphosate- and glufosinate-resistant maize varieties commercially available under the trade names RoundupReady®, Herculex I® and LibertyLink®.

The term “useful plants” is to be understood as including also useful plants which have been so transformed by the use of recombinant DNA techniques that they are capable of synthesising one or more selectively acting toxins, such as are known, for example, from toxin-producing bacteria, especially those of the genus Bacillus.

Examples of such plants are: YieldGard® (maize variety that expresses a CryIA(b) toxin); YieldGard Rootworm® (maize variety that expresses a CryIIIB(b1) toxin); YieldGard Plus® (maize variety that expresses a CryIA(b) and a CryIIIB(b1) toxin); Starlink® (maize variety that expresses a Cry9(c) toxin); Herculex I® (maize variety that expresses a CryIF(a2) toxin and the enzyme phosphinothricine N-acetyltransferase (PAT) to achieve tolerance to the herbicide glufosinate ammonium); NuCOTN 33B® (cotton variety that expresses a CryIA(c) toxin); Bollgard I® (cotton variety that expresses a CryIA(c) toxin); Bollgard II® (cotton variety that expresses a CryIA(c) and a CryIIA(b) toxin); VIPCOT® (cotton variety that expresses a VIP toxin); NewLeaf® (potato variety that expresses a CryIIIA toxin); Nature-Gard® Agrisure® GT Advantage (GA21 glyphosate-tolerant trait), Agrisure® CB Advantage (Bt11 corn borer (CB) trait), Agrisure® RW (corn rootworm trait) and Protecta®.

The term “useful plants” is to be understood as including also useful plants which have been so transformed by the use of recombinant DNA techniques that they are capable of synthesising antipathogenic substances having a selective action, such as, for example, the so-called “pathogenesis-related proteins” (PRPs, see e.g. EP-A-0 392 225). Examples of such antipathogenic substances and transgenic plants capable of synthesising such antipathogenic substances are known, for example, from EP-A-0 392 225, WO 95/33818, and EP-A-0 353 191. The methods of producing such transgenic plants are generally known to the person skilled in the art and are described, for example, in the publications mentioned above.

The term “locus” of a useful plant as used herein is intended to embrace the place on which the useful plants are growing, where the plant propagation materials of the useful plants are sown or where the plant propagation materials of the useful plants will be placed into the soil. An example for such a locus is a field, on which crop plants are growing.

The term “plant propagation material” is understood to denote generative parts of the plant, such as seeds, which can be used for the multiplication of the latter, and vegetative material, such as cuttings or tubers, for example potatoes. There may be mentioned for example seeds (in the strict sense), roots, fruits, tubers, bulbs, rhizomes and parts of plants. Germinated plants and young plants which are to be transplanted after germination or after emergence from the soil, may also be mentioned. These young plants may be protected before transplantation by a total or partial treatment by immersion. Preferably “plant propagation material” is understood to denote seeds.

The compounds of formula (I) can be used in unmodified form or, preferably, together with carriers and adjuvants conventionally employed in the art of formulation.

Therefore the invention also relates to compositions for controlling and protecting against phytopathogenic microorganisms, comprising a compound of formula (I) and an inert carrier, and to a method of controlling or preventing infestation of useful plants by phytopathogenic microorganisms, wherein a composition, comprising a compound of formula (I) as active ingredient and an inert carrier, is applied to the plants, to parts thereof or the locus thereof.

To this end compounds of formula (I) and inert carriers are conveniently formulated in known manner to emulsifiable concentrates, coatable pastes, directly sprayable or dilutable solutions, dilute emulsions, wettable powders, soluble powders, dusts, granulates, and also encapsulations e.g. in polymeric substances. As with the type of the compositions, the methods of application, such as spraying, atomising, dusting, scattering, coating or pouring, are chosen in accordance with the intended objectives and the prevailing circumstances. The compositions may also contain further adjuvants such as stabilizers, antifoams, viscosity regulators, binders or tackifiers as well as fertilizers, micronutrient donors or other formulations for obtaining special effects.

Suitable carriers and adjuvants (auxiliaries) can be solid or liquid and are substances useful in formulation technology, e.g. natural or regenerated mineral substances, solvents, dispersants, wetting agents, tackifiers, thickeners, binders or fertilizers. Such carriers are for example described in WO 97/33890.

The compounds of formula (I) or compositions, comprising a compound of formula (I) as active ingredient and an inert carrier, can be applied to the locus of the plant or plant to be treated, simultaneously or in succession with further compounds. These further compounds can be e.g. fertilizers or micronutrient donors or other preparations which influence the growth of plants. They can also be selective herbicides as well as insecticides, fungicides, bactericides, nematicides, molluscicides or mixtures of several of these preparations, if desired together with further carriers, surfactants or application promoting adjuvants customarily employed in the art of formulation.

A preferred method of applying a compound of formula (I), or a composition, comprising a compound of formula (I) as active ingredient and an inert carrier, is foliar application. The frequency of application and the rate of application will depend on the risk of infestation by the corresponding pathogen. However, the compounds of formula (I) may also penetrate the plant through the roots via the soil (systemic action) by drenching the locus of the plant with a liquid formulation, or by applying the compounds in solid form to the soil, e.g. in granular form (soil application). In crops of water rice such granulates can be applied to the flooded rice field. The compounds of formula (I) may also be applied to seeds (coating) by impregnating the seeds or tubers either with a liquid formulation of the fungicide or coating them with a solid formulation.

A formulation, i.e. a composition comprising the compound of formula (I) and, if desired, a solid or liquid adjuvant, is prepared in a known manner, typically by intimately mixing and/or grinding the compound with extenders, for example solvents, solid carriers and, optionally, surface-active compounds (surfactants).

The agrochemical formulations will usually contain from 0.1 to 99% by weight, preferably from 0.1 to 95% by weight, of the compound of formula (I), 99.9 to 1% by weight, preferably 99.8 to 5% by weight, of a solid or liquid adjuvant, and from 0 to 25% by weight, preferably from 0.1 to 25% by weight, of a surfactant.

Whereas it is preferred to formulate commercial products as concentrates, the end user will normally use dilute formulations.

Advantageous rates of application are normally from 5 g to 2 kg of active ingredient (a.i.) per hectare (ha), preferably from 10 g to 1 kg a.i./ha, most preferably from 20 g to 600 g a.i./ha. When used as seed drenching agent, convenient rates of application are from 10 mg to 1 g of active substance per kg of seeds. The rate of application for the desired action can be determined by experiments.
